1. A system for remotely managing electric power transfer, the system comprising:
a power source;
an external electric vehicle charging device configured to transfer electric power from the power source to an electric vehicle;
a smart meter device comprising a first hard-wire connector coupling the smart meter device to the power source and a second hard-wired connector coupling the smart meter device to the external electric vehicle charging device, wherein the smart meter device is configured to couple the external electric vehicle charging device to the power source, and configured to control the electric power transferred to the electric vehicle by the external electric vehicle charging device by transmitting, via a wireless network, remote commands and electrical charging data to and from the external electric vehicle charging device respectively; and
a smart meter control server communicatively coupled to the smart meter device, wherein the smart meter control server is configured to receive user commands transmitted, via a mobile network, from a mobile device operated by a user;
wherein the smart meter control server is configured to remotely control the smart meter device by:
transmitting a start command to the smart meter device in response to receiving a first user command from the user, wherein the start command causes the smart meter device to permit the external electric vehicle charging device to start the electric power transfer;
transmitting a stop command to the smart meter device in response to receiving a second user command the user, wherein the stop command causes the smart meter device to prevent the external electric vehicle charging device from continuing the electric power transfer.
